RCC is the basis of major high rise infra of country and the world, but the major loophole working with RCC is corrosion of embedded steel. This corrosion not only causes premature deterioration of the structure, but also makes the structure unserviceable or fragile and shabby. Geopolymer is an inorganic polymer, an alkali-activated binder which has gained worldwide interest and its high anticorrosion property made it a novel coating material. The reaction of solid aluminosilicate material with highly concentrated aqueous alkali hydroxide or silicate solution to produce a synthetic alkali aluminosilicate material generically called “geopolymer” and can be compared in performance with the traditional cementitious binders in a range of applications, but with the added advantage of significantly reduced greenhouse emissions. The geopolymer solution can be tailored by correct mix and processing to optimise properties such as flexibility, adhesion and to offer excellent corrosion resistance properties with reduced cost for given coating applications.Therefore, by considering the advantages offered by geopolymer binder such as greener material, good corrosion and alkali, acid resistance, fire resistance and also excellent adhesion to steel substrate with high electrical insulating effects, the geopolymer binder is chosen with different kind of aluminosilicate materials.Twenty different geopolymer based compositions using fly ash, OPC, Microsilica, Rice husk ash, Clay, China Clay, Kaolin, Ferrosilicon Powder, Vanadium Pentoxide, Silica fume and Fe2O3 as functional pigments and fillers were formulated and brush able coating materials were synthesised. A combination of Binder + Fly ash + Clay + Iron oxide yellow and Binder + Fly ash + Rice husk ash + Iron oxide yellow individually have passed all the examinations as per the experimental conditions adopted in the present study and may be very well utilized for preventing or decelerating the corrosion rate of steel rebars in concrete.
